Major Light

LIGHTS

light_major

A major light is a light that is intended to be seen at extended distances and will indicate the presence of prominent land masses or provide guidance into harbours or rivers. This tag is used where the supporting structure is not specified, otherwise the seamark:type tag should take the value of the supporting structure (most often "landmark")

Minor Light

LIGHTS

light_minor

A minor light is a short-range light that marks obstacles in the same way as lighted buoys and beacons, otherwise the seamark:type tag should take the value of the supporting structure (most often "pile")

Light Vessel

LITVES

light_vessel

A distinctively marked vessel anchored or moored at a charted point, to serve as an aid to navigation. By night, it displays a characteristic light(s) and is usually equipped with other devices, such as fog signal, submarine sound signal, and radio-beacon, to assist navigation.

Light Float

LITFLT

light_float

A boat-like structure used instead of a light buoy in waters where strong streams or currents are experienced, or when a greater elevation than that of a light buoy is necessary.

Attributes

Colours

Lights have a single colour, except those with Alternating characters, which have two colours.
